IRRIGATION GATE.

Application filed September To all whom it may concern Be it known that I, THOMAS C. JAMESON, a citizen of the United States, residing at Gonzales, in the county of Monterey and State of California, have invented a new and useful Improvement in Irrigation Gates, of which the following is a specification.

This invention relates to means for closing the ends of conduits, and especially to that type of closures known as irrigation or flume gates.

One of the objects of the present invention is to provide a simple, substantial and cheaply operated closure for the ends of irrigation pipes or like conduits, and especially to provide a gate-like closure which may be used in conjunction with iron, wood or concrete pipes, and which is self-seating and capable of automatically taking up wear.

Another object of the invention is to pro vide means for raising or lowering the gate and for supporting the same at intermediate points to regulate the flow of water through the gate.

Further objects will hereinafter appear.

The invention consists of the parts and the construction, combination and arrangement of parts as hereinafter more fully de' scribed and claimed, having reference to the accompanying drawings, in which-- Fig. 1 is a cross section of an irrigation ditch showing the position of the gate.

Fig. 2 is an enlarged central vertical longitudinal cross section of the gate.

Fig. 3 is a plan view of the gate.

Referring to the drawings in detail, A indicates an irrigation ditch and 2 a conduit or pipe extending through one of the banks of the ditch and provided for the purpose of tapping the ditch or diverting the flow of the water contained in the same. The conduit may be constructed of iron, wood, concrete or any suitable material. It is preferably provided with an end plate 3 to retain it against endwise movement. The gate forming the subject matter of the present invention is generally indicated at 4-. lit consists of a fiat metal plate, the sides of which are flanged as at P. The gate proper is connected with a pair of arms 5 which are pivotally supported on the conduit as at 6. There is in reality only one arm employed but this is bail-shaped and the outer end of the bail-shaped arm is pivotally attached to the side flanges of the'gate as at 7. The gate is otherwise provided with Specification 01 Letters Patent.

a series of pins 8, which are provided for the purpose of supporting the gate in a partially open or a partially closed position. The gate constructed as here shown is indeed simple to operate. If it is desired to partially open the gate, for instance so that it will assume the position shown in Fig. 2, it is only necessary to raise the bail-shaped arms 5 in an upward direction and to partly t1lt the gate so that the pins 8 will clear the upper end of the pipe. The gate is then tilted to a vertical position and one of the pins will rest on the upper side of the pipe and thereby support the gate. It may be raised to practically any position desired; the number of positions permissible being only regulated by the number of pins employed. As the gate is hingedly supported in the arms 5, it is obvious that it becomes self-seating with relation to the end of the pipe as the water in the ditch will exert sufiicient pressure to maintain it in close engagement with the end of the pipe. Again,

by slightly slotting the outer ends of the.

arms 5, as shown at 7*, it is obvious that wear will be automatically taken care of.

While certain features of the presentinvention are more or less specifically illustrated, I wish it understood that various changes in form and proportion may be resorted to within the scope of the appended claims, similarly that the materials and finish of the several parts employed may be such as the experience and judgment of the manufacturer may dictate or varying uses may demand.

Having thus described my invention, what I claim and desire to secure by Letters Patent is- 1. In a device of the character described the combination with a conduit of a gate forming a closure for one end thereof, a pair of arms pivotally supported by the conduit, a pivotal connection between said arms and the gate to permit raising and lowering of the gate with relation to the end of the conduit, and means for supporting the gate at points intermediate full opening and full closure, said means comprising a plurality of interposed superposed pins secured to the inner face of the gate and engageable with the upper end of the conduit.

2. In a device of the character described the combination with a pipe of a gate forming a closure for one end thereof, a bailshaped arm pivotally attached to the pipe,

' said arms being slotted at their outer ends, sition and also adapted to support the gate pins on the gate projecting through said at pointsintermediate full opening and slots and forming a pivotal connection befull closure. V tween the bail-shaped arm and the gate, to Intestimony whereof I have hereunto set 5 permit raising and lowering of the gate my hand in the presence of two subscribing 15 side flanges "formed on the gate forming a Witnesses.
